This customer case study highlights the successful application of 316Ti stainless steel pipes (EN 1.4571) supplied by KCM SPECIAL STEEL for low-pressure air transport (≤2 bar gauge pressure) in a European sewage treatment plant. Faced with frequent corrosion failures in carbon steel pipes due to moisture, chlorides, and hydrogen sulfide, the plant sought a durable, cost-effective solution. KCM delivered 316Ti pipes stabilized with titanium to prevent weld decay, ensuring compliance with EN 1.4571 standards and 2% optimized alloy density for enhanced performance.
Key outcomes include zero leaks/corrosion after 24 months, €48,000/year maintenance savings, and full compliance with third-party inspections (PMI, dimensional checks, hydrostatic tests). The project underscores 316Ti’s superiority in aggressive environments, offering 25–30% lower lifecycle costs than 316L. KCM’s precision manufacturing, rigorous quality control, and certified logistics ensured seamless installation and long-term reliability.
This case validates 316Ti stainless steel as an ideal choice for cost-sensitive, corrosive applications, aligning with EU sustainability goals through recyclability and reduced downtime.
